Determining Operation Settings
On the second screen of the control (SETUP) under the Field Setup header, input the estimated Ton/Acre yield
of the field (1.75), desired driving speed in mph (usually matched w/ baler speed
→
6.0mph), swath width in ft.
(30.0).
After inputting the field setup settings, input the moisture setup settings the starting moisture content (8.0%),
desired moisture content (15.0%), and the desired water temp (240F).
Based on the condition and size of the windrow, input under the Machine Setup header the number of trip
sections that are active (5-11). Input the number of tips installed (65, 70, 75, 80, or 85), and input the size of
the tip (either 5 for MW5’s or 11 for MW11’s) *standard size is 11. In most situations, the number of tips
installed and the tip size will not need to be changed often, maybe occasionally when going from a heavy
cutting to a light cutting.
Based on the inputted values for the field, moisture, and machine setup settings, the Target GPM and SET
PRESSURE values will be calculated. **Depending upon the number of tines installed (usually a function of
windrow width) and the Target GPM, reference the tip charts to confirm that your tip size is correct. If you tend
to operate at lower GPM’s (<9GPM), it may be beneficial to run the MW5 tips. **the SET PRESSURE value
should be between 300 and 1200 PSI. If your calculated pressures are outside of those ranges, modification
may need to be made to i) desired driving speed, ii) trip sections, or iii) # of tips.
Settings Pressures
Once the Target GPM and Set Pressure values are derived, adjust the trip sections for the windrow conditions.
With the reel lowered so it is 12” off the ground and the system primed, activate the arm override button and
turn the PTO on. Run the PTO at approximately 800 rpm. Adjust the pressure relief valve at the rear of the
pump until the gauge matches, approxi/- 50 PSI, the SET PRESSURE value.
After the pressure is set, turn off the arm override. This will cause the flow to divert back to the tank until the
reel is lowered to the operating position.
With arm switch active or switch override selected, increase PTO speed to approximately 750-800 rpm
Adjust pressure regulator valve until the desired pressure setting is achieved
Warming Up System
To reduce a waste of water, the warming valve can be used to bypass the water coming out of the heaters to
the tank until it reaches a preset temp, at which time the valve will close and water will be directed to the reel.
Start with the reel raise
d 12” above the ground, system primed, arm override button activated, and the warming
valve button activated.
Turn on Heater 1 and Heater 2. The buttons will show blue, but the indicator lights on the heaters will not be
illuminated, indicated that the heater are not firing.
Turn on the PTO and run at approximately 800rpm. As soon as a flow meter reading is measured, the heaters
will turn on and start heating, indicated by the indicator lights being illuminated on the heaters.
Since the warming valve is activated (open), the heated water will bypass to the tank until the output
temperature reaches 200F. Once the output temperature reaches 200F, the warming valve will automatically
become inactive and close, forcing the heated water out of the reel.
The output temperature can be observed on the main screen of the controller on the lower left side, below the
target temperature. Once the system has reached 205F, it will display an
“OK” operating status (shown in the
top center of the main screen)
. Once the system reaches 205F or “OK”, you can turn off the arm override
button, which will cause the 2 way valve to open and cause the heaters to turn off. At this point, you will still
see a flow meter reading as the pump pumps water from the tank through the pump and back to the tank.
